So far, just wildlife. With the new Z8, I'm wanting to learn how to do vide for short wildlife snippets in between shooting images.
This is a very good value for a top notch, large capacity card. Highly recommended. I have a couple 325 gig Delkin Black, and a pair of the readers shown on the listing too. Delkin is top notch product, and they stand behind their products.
you need to read the fine print. the MAXimum write is 1540. you want to use the sustained or MINimum write speed to evaluate the card.

What specs should I check to see the difference? That way I can learn for future comparisons. I have a Cobalt 325GB, I'm thinking of the POWER card as a second one.
Thanks!you need to read the fine print. the MAXimum write is 1540. you want to use the sustained or MINimum write speed to evaluate the card.
also note this thread, looks like they just issued a newer version of this card:
New Delkin Power G4 cards
https://www.bhphotovideo.com/c/product/1769005-REG/delkin_devices_dcfxbp128g4_128gb_power_cfexpress_memory.html/overview Saw these today when I was about to buy a pair of Power 128GB CFe cards. Same $109 price and promising 800 mb/s minimum write speed seems pretty freaking fantastic. Looks...
You have to look at the fine print and look for the minimum sustained write speed. The up to speeds on the card is the theoretical burst speeds.
That's a great price on a 1TB card. The 650 GB and larger cards are just short of the same speed as the Delkin Black. I have the 1TB card and have never had any issues with overheating during burst shooting. I have not tested it with video - but the minimum sustained write speed is fast enough that it should not be a problem.
Note MB is mega BYTES per second (capital B).
Thanks!!while don't sue me if i'm wrong, the key part of the spec is:
Note MB is mega BYTES per second (capital B).
and if you look at the bitrates needed by various video formats supported by the z9, you'll fine the highest bitrate is 5780 Mbps. That's mega BITS per second (lowercase b), so divide by eight to get 722.5MB/s.

so basically anything that can sustain 800MB/s should work fine for whatever video the Z9 can throw at it.
Video requires less minimum sustained write speeds (850MB/s) then stills which is at least 1300MB/s. The numbers on the card are theoretical MAX write speeds.
they publish a minimum sustained as well ( 1490 MB/s for the card Joel was looking at ).
The Z9 has PCIe 3.0 2 Lane and has a Max speed of 1.8GB/s. You can shoot unlimited stills with an adapted M.2 2230 SSD that writes in the 3.5GB/s range and can shoot lossless Raw with an unlimited buffer. I've seen it. If you shoot with a card with a min sus write speed of LESS then 1300MB/s in raw modules you buffer will be pretty then 80fps before slowing to 15fps. 1300-1500MB/s and your move that buffer to about 82-84fpsthey publish a minimum sustained as well ( 1490 MB/s for the card Joel was looking at ).
i suspect maximum the z9 can actually _sustain_ is about 15 fps (maybe a bit under that) lossless raw, which 15 fps * 65MB = 975 MB/s
EDIT: i kinda wonder if the z9 only gives the cfe-b one lane
If it’s possible, why isn’t it offered by manufacturers? Does it get too hot?
the weird thing is i’ve personally verified all the following cards can sustain fast enough speeds to do 20fps lossless but none of them come close, in camera
I'm not talking about CFE type B cards. I'm taking about an M.2 2230 SSD drive that writes at 3500MB/s placed in a CFE adapter for unlimited buffer. The M,2 drives are far superior then CFE type B cards.
Here is the wire up link of the one used about a year ago. Then they ran about $50 I believe
